The numbers
A full rewire in Limerick generally costs €5,000 to €9,000. Doing one area only, such as a kitchen or a single floor, runs €2,000 to €4,500. Where your house sits inside those ranges comes down to its size, its age, and how easily cables can be run through it.
| Work | Guide cost |
|---|---|
| One room or area rewired | €2,000–€4,500 |
| Three-bed semi, full rewire | Lower half of €5,000–€9,000 |
| Larger, older or extended house | Top of the range, sometimes above it |
| Consumer unit on its own | €350–€600 |
A phone quote for a rewire is a guess. Until someone has lifted a floorboard and looked at the board, any number is either padded for safety or destined to rise.
Do you need a rewire, or just a new board?
This is the question worth answering before you budget for anything, because the difference is roughly €400 against €7,000.
A board upgrade is usually enough when
The cabling is PVC and in good condition, circuits pass testing, the earthing is sound, and the only real problem is an ageing board with no RCD protection and no spare capacity. That is most Limerick houses built from the mid-1980s onwards. A consumer unit upgrade at €350 to €600 solves it.
A rewire is the honest answer when
The cable itself has failed or is unsafe: rubber insulation, no earth on the lighting circuits, or a patchwork of alterations that cannot be tested as one installation. No board, however modern, makes bad cable safe.
How you find out for certain
A periodic inspection report, at €150 to €300. An electrician tests every circuit and tells you in writing what is sound and what is not. On an older house it is the cheapest money you will spend, because it turns a €7,000 guess into a decision.
Signs the cable itself is the problem
- Rubber-sheathed or fabric-covered cable visible at the board or in the attic
- Lighting circuits with no earth wire, common in pre-1970s wiring
- Round-pin sockets, or sockets screwed to the skirting
- A board with fuse wire rather than switches
- Sockets or switches that are warm to touch, or discoloured
- Repeated tripping that nobody has been able to trace
One of these on its own is worth an inspection. Three or more usually means a rewire.
What makes one Limerick house dearer than the next
City terraces
Solid walls and solid floors mean cables have to be chased into plaster rather than run under boards. That is slow work and it leaves more making good behind it. These are the houses at the top of the range.
Estate housing from the seventies and eighties
Usually the most straightforward. Timber floors upstairs, an accessible attic, and a predictable layout mean cable routes already exist. Most three-bed semis in the city suburbs and the county towns land here.
Rural and extended houses
West Limerick farmhouses and anything extended two or three times over the decades take longer, because each phase was wired differently and the boundaries between them have to be worked out before anything is priced.
How many points you ask for
The single biggest thing you control. A house wired in 1978 might have two sockets in a bedroom that now needs six. Adding them during a rewire costs very little. Adding them next year means opening the walls again.
What actually happens, week by week
Before anything starts
A survey, then a written itemised price that states plainly whether making good and certification are included. Ask both questions directly.
First fix
New cable is run to every socket, switch and light, with floors up and chases cut. This is the disruptive part. Most of the old installation usually stays live while it happens.
Second fix
Sockets, switches, fittings and the new consumer unit go on, and the old wiring comes out.
Testing and certification
Every circuit is tested individually and a Completion Certificate is issued. Only a registered contractor can issue one, and you will be asked for it when you sell.
A typical three-bed takes one to two weeks. Larger or occupied houses take longer because the work is phased around you.
Rented and student houses
Limerick has an unusual amount of housing let room by room, particularly around the university. Those installations age faster than family homes: more appliances, more extension leads, more tenants who do not know which breaker is which.
If you let a property, get a periodic inspection report before deciding anything. Landlords often find a partial rewire of the kitchen and a board upgrade solves the problem for a fraction of a full rewire, and it can be scheduled between tenancies rather than during one.
Can you keep living there?
Usually yes, if the work is phased. Expect a few days where the kitchen is awkward, one short full power-off when the board is changed, and dust throughout. Tell the contractor at survey stage if anyone in the house relies on powered medical equipment, or works from home on fixed days, so it can be planned around.
Get a rewire surveyed
Send your eircode, roughly when the house was built, and photos of the fuse board and a couple of sockets. That is enough to know whether you are looking at a board upgrade or a rewire before anyone charges you for a visit.
